capituliformis, and many of the microscopic details as well. The 

 remarkable balls of paraphyses inclosing the urediniospores are 

 similar, and the colorless teliospores also. As in the former 

 species the surest way to find the teliospores is to crush a ball of 

 paraphyses, taken from a well-matured group of sori. The 

 teliospores are usually found germinated, which obscures their 

 true shape.

 This is the first record of the rust for the West Indies. The 

 host is furthermore a new one for the species. Only uredinia 

 were found, the spores measuring a trifle larger than usual, 18- 

 23 by 23-32 /x. Sections of the. sori showed a few peripheral 

 paraphyses, not rising above the spore mass.

 The Sydows have recently pointed out (Monog. Ured. 3: 524.
